Calix: Mainland China has not signed the CARF framework, and domestic users are currently enjoying a "sweet window period." FinTax founder Calix pointed out in an interview with Wu that because mainland China has not yet signed the CARF framework, overseas cryptocurrency transaction data will not be automatically exchanged with domestic tax authorities. This provides a short-term arbitrage "sweet window" for mainland tax residents compared to the bank system covered by CRS. However, he also warned that the lack of data exchange does not mean legal exemption from taxes. Converting crypto assets into fiat currency may still be tracked; and as the scale of wealth carried by RWA, stablecoins, and other crypto assets continues to grow, global crypto asset taxation is an inevitable trend. Users should not hold false hopes but should use this window period to make long-term plans. The video and written content only represent the interviewee's views and do not reflect Wu's opinions.
